I just recently started reloading for my AR and have different powders. I am now using CFE223 and 55 grain fmj bullets. The data calls for about 26 grains for starting loads. I read on many forums and saw lots of people using 25 grains so I started there. It had a lot more kick than my loads using 4064 so I went down to 24, 23, 22, and then 21. I am getting good performance out of the 21 grain load so I am wondering if there is a reason to go back up. I am reloading for plinking shooting at a maximum of 100 yards using a red dot sight so I am not looking to put these in a real tight group. Your thoughts please.
